Question

Im going to implment password reset functionality. First user enters email into the form. Then click submit. On the server side I check if the email is correct and if the user exists in database and if so then I redirect to the next page (in fact it is the same page with questry string parameter ?step=2).

I cant use session because of loadBalancer. What is the best way to keep users mail ?

thanks for any help

Answer 1

If it is the same page then it should be fairly trivial. You could add a hidden input field and append it to your form so in your button click handler:

protected void Button1_Click(object sender, EventArgs e)
{
    string email = email.Text;
    //Check database etc

    HtmlInputHidden hidden = new HtmlInputHidden();
    hidden.Value = email;
    hidden.ID = "hiddenemail";
    form1.Controls.Add(hidden); // Where form1 is the ID of a form with runat=server
}

Or event better if there was an existing server control say a label that you could use you would just do:

protected void Button1_Click(object sender, EventArgs e)
{
    string email = email.Text;
    //Check database etc
   Label1.Text = email; // Where Label1 is the ID of a ASP:Label on your page
}
